Title: Cell traffic monitor
Inventor: YAMANAKA NAOAKI
IPC: H04Q3/00
Filed: 1990-10-26
Abstract: PURPOSE:To realize the cell traffic monitor simply realized by a small hardware by comparing and discriminating a count of a 2nd counter circuit with a threshold level over a prescribed time. CONSTITUTION:Number of valid cells detected for a just preceding m-cell time, i.e., in a short time is counted in a 1st counter circuit 4. Thus, the count of the 1st counter circuit 4 is fetched in a 2nd delay circuit 31 and a 2nd counter circuit 41 and accumulated intermittently for the m-cell time each and when the content of the 2nd counter circuit 41 is subtracted by a delay output of the 2nd delay circuit 31, the count of the 2nd counter circuit 41 is the total sum of valid cells detected for a preceding M(=mXn)-cell time, that is, for a long time. Then the total sum is compared and discriminated by a threshold level (N) to attain polishing over the M(=mXn)-cell time. Thus, the cell traffic monitor is realized, which is simply realized with a small practical hardware.

Title: Projection liquid crystal display device
Inventor: UMEZAWA TOSHIMITSU
IPC: G02F1/1335
Filed: 1990-10-26
Abstract: PURPOSE:To reduce the lowering of contrast in an image projected on a screen due to external light by providing a polarizing means at the front face of a screen. CONSTITUTION:External light, reaching a screen 5 being damped into about a half at the time of passing a polarizing means 8 provided at the front face of the screen 5, is reflected by the screen face and further damped into about a half at the time of passing the polarizing means 8 again. The reflection quantity of the external light is thereby reduced into about a quarter compared to the case without a polarizing means. On the other hand, image light emitted from a liquid crystal panel 3 and projected on the screen 5 is hardly damped by the polarizing means 8 by setting the polarizing direction of the polarizing means 8 provided at the front face of the screen 5 to be parallel to the direction of polarized waves emitted from the liquid crystal panel 3.

Abstract: PURPOSE:To expose accurately a specified epitaxial layer surface, by forming an anti-etching layer on the surface of a substrate desired to be exposed, and obserbing wherther this anti-etching layer is exposed or not, during the etching of the epitaxial layer formed on the substrate containing the anti-etching layer. CONSTITUTION:On a GaAs epitaxial layer 13 containing an island-shaped anti- etching layer 15a, a GaAs epitaxial layer 17 (a second epitaxial layer 17) is grown. A resist layer is formed on the second epitaxial layer 17, and a mask is obtained which exposes a region surface corresponding to a substrate on which an island-shaped, for example, anti-etching layer 15a of the second epitaxial layer 17 is formed, and a region surface which is required to be removed for forming a semiconductor element. Then by using etching liquid of, for example, an ammonia-hydrogen peroxide system, etching for the second epitaxial layer 17 exposed from a window 21 is performed in several stages. Under a microscope, the progress of etching of the second epitaxial layer 17 in the window 21 is observed after each etching stage. When the island shaped anti-etching layer 15a is exposed, the etching for the second epitaxial layer 17 is interrupted.

Patent JP-H02133735-A (JP)
Title: Indoor environmental control system
Inventor: HOSHINO TETSUNORI
IPC: F24F7/007
Filed: 1988-11-14
Abstract: PURPOSE:To eliminate useless operation or the continuance of ventilating operation to be carried out even after a room is satisfactorily ventilated by driving automatically a ventilating fan interlocked with the light out detecting operation of a sensor and halting the operation of said ventilating fan in automatic mode after a preset time has passed after having left the room. CONSTITUTION:When entering a room, a switch S is turned on and a constantly closed contact b1 of a relay M2 is under an off-state by the lighting detection operation of a sensor Se. As a result, a ventilating fan F remains unconnected with a power source 1 so that the drive of the ventilating fan F may be prevented. Then, when leaving the room, the switch S is turned off by manipulating the knob of the door, which keeps a constantly open contact a1 of a relay M1 under an off-state, thereby putting out a lighting device L. Therefore, the light out detecting operation of the sensor Se keeps a constantly open contact a2 of the relay M2 under an off-state as well. However, an off-delay type timer T keeps the constantly open contact a1 under an on-state during the preset time. Moreover, the light out detecting operation of the sensor Se returns the constantly closed contact b1 to the off-state, which drives the ventilating fan F and halts its operation after a preset time has passed.

The upper layer plating of an Fe-B alloy contg., by weight, 97 to 100% Fe and 0.001 to 3% B is thereafter applied on one or both surfaces of the hot dip galvanizing steel sheet subjected to the alloying treatment to 0.5 to 10g/cm<2> deposition. The plated steel sheet is heated for 20 seconds to 15 hours in the temp. range of >=250 deg.C and below the m.p. of the zinc in a furnace in which a nonoxidative or reducing atmosphere is maintained.
